Patent GB-822368-A (GB)
Title: Process for the manufacture of chlorine dioxide
IPC: C01B11/02
Filed: 1956-10-02
Abstract: Chlorine dioxide is prepared by reacting more than 2 mols hydrochloric acid per mol. sodium chlorate with a solution of sodium chlorate at a temperature below +10 DEG  C., e.g. down to -25 DEG C., separating the precipitated sodium chloride, and desorbing the chlorine dioxide and chlorine from the solution thus formed by the action of an inert gas and/or heat.  A fraction of the residual solution may be used for preparing <PICT:0822368/III/1> the solution of chlorate for subsequent manufacture.  Solid NaClO3 is fed to dissolver 1 and dissolved in residual liquor from previous manufacture recycled from pump 5.  The NaClO3 solution passes to reactor 2 maintained at - 5 to - 15 DEG  C., where aqueous HCl is introduced at spaced points through the reactor.  The molar ratio HCl/NaClO3 should be more than 2.8, but should not exceed 3.2.  The solution is withdrawn at the bottom of reactor 2 through pipe 8 to the top of desorption tower 4, while NaCl is decanted through filter 3 and is washed with recycled residual liquor from pump 5. Cl2/ClO2 in ratio about 0.6 are desorbed in tower 4, by combined action of air entering at 9 and water at ambient temperature circulating through coil 10 and pass out at 14.  Part of the air is introduced at 11 and sweeps through dissolver 1 and over the top of reactor 2, and thence by pipe 13, while the remainder is introduced at 17 into auxiliary desorption tower 18 and thence by pipe 16.  The solution is withdrawn from tower 4 by pump 5 and, apart from the portions recycled to dissolver 1 and to filter 3, is purged at 15 to remove water, or passed to the top of auxiliary desorption tower 18 heated by hot water at 50-60 DEG  C. in coil 20 and supplied with air at 17.  The resulting solution passes down HCl dissolver 21 having drip-plate section 21a, water-cooled section 21b and brine-cooled section 21c, while HCl gas enters from pipe 22.  Precipitated NaCl is removed at 23 and the HCl is pumped to pipe 7.  The process may be carried out as a batch operation with reaction and desorption being effected in the same vessel.  In an alternative continuous process gaseous HCl is introduced at spaced points directly into reactor 2 which has a brine cooling coil.  As a further alternative a portion of the recycle liquor may be withdrawn and replaced with HCl solution.

Title: Heat set inks and vehicles
Inventor: HORN LUDWIG PAUL
IPC: C09D11/02
Filed: 1964-07-30
Abstract: A heat set printing ink comprises a diluent, a pigment, and a vehicle obtained by combining the reaction product from a polyvalent metal alcoholate of a C1- 5 alkanol and a monohydroxy glycol ether, a monohydroxy glycerol ether, or an alcohol having more than 8 carbon atoms with a resinous material containing free carboxyl groups. Preferred metal alcoholates derive from metals having a valency of 3 or more, e.g. Al, Ti, Zr, Fe and Cr, and from C1- 5 alkanols, e.g. ethyl, propyl, isopropyl, butyl, isobutyl, pentyl or isopentyl alcohols. Suitable for reaction with these are e.g. the methyl, ethyl, butyl, hexyl, and phenyl monoethers of ethylene, diethylene or triethylene glycol, or oxo alcohols, e.g. tridecyl or octyl alcohol, or fatty alcohols, e.g oleyl alcohol. Sufficient hydroxy compound should be provided to replace from one to all of the original alcoholate groups on the metal.  Usually an amount of metal alcoholate-hydroxy compound product equal to 0.2-15 wt. per cent of the resin component is satisfactory.  Suitable resins are alkyd, oil-modified alkyd, rosin-modified alkyd or rosin-modified phenolic resins, or rosin esters, and fumaric acid-modified polymerized unsaturated refinery by-products.  In examples products from the reactions of aluminium isopropoxide with diethylene glycol monohexyl ether, of aluminium ethylate with diethylene glycol monobutyl ether or tridecyl alcohol, and of titanium isobutylate with propylene glycol monomethyl ether or tridecyl alcohol, are diluted with an aliphatic hydrocarbon solvent of boiling point 450-510 DEG  F. and mixed with a solution of a pentaerythritol tetraester of a dimerized abietic acid in the same solvent.

Title: Improvements in or relating to the manufacture of treatment of artificial filaments, threads, yarns, and like materials
IPC: D01F2/28
Filed: 1935-11-07
Abstract: <PICT:0465780/IV/1> The tension in artificial filaments, threads and yarns is maintained constant in processes in which the running materials are subjected to the action of softening agents, by controlling the conditions under which the materials are softened by the tension itself.  For example, the filaments or the like may act directly on a dynamometer which in turn operates a relay, e.g., a photo-electrically controlled relay.  The relay may cause a steam valve to open wider when steam is used as the softening agent, or may cause a pump to introduce additional and more concentrated softening agent into the bath when a solution of a softening agent, such as dioxane, is being used.  In the Figure, the thread 1 enters the bath 2 and passes around the pulleys 7, 8, 9, of a dynamometer.  A solution of dioxane is kept in circulation through the bath by means of a suitable pump and conduits 4, 5. The pulley 8 of the dynamometer operates a disc 11 which is movable in the path of a beam of infra red rays passing from the source 12 to the photo-electric cell 13. The cell controls an electric motor 15 connected to a pump supplying a solution of dioxane to the bath.  This solution has a concentration of 3--8 per cent higher than that in the bath.  In operation, an increase in tension in the thread causes the mechanism attached to the dynamometer to intercept the beam of infra red rays falling on the photo-electric cell, thereby causing the motor 15 to start up and pump more concentrated softening agent into the bath to counteract the increase in tension.
